Description
Technical field
The present invention relates to a kind of valve, and in particular to a kind of more diversified balanced valve of performance.
Background technology
Balanced valve is under the conditions of hydraulic regime, plays adjusting static state, the valve of dynamic equilibrium.In the past traditional balanced valve
It has been devoted to make moderate progress in the performance of adjustment, but often ignores the architectural characteristic of balanced valve in itself, so that
The repertoire of its balanced valve can not be brought into play.
The content of the invention
In consideration of it, it is an object of the present invention to provide a kind of more diversified balanced valve of performance, it is intended to by tradition
The improvement of balancing valve structure balances the defects of valve performance is single in the past to overcome.
In order to reach foregoing invention purpose, the technical solution taken is as follows：
A kind of balanced valve, including valve deck, valve rod and valve body, the valve deck are connected with valve body, and the valve rod is arranged on institute
The inside of valve deck and valve body is stated, wherein, it is provided with valve between the end for the valve rod being inserted into inside the valve deck and the valve deck
Lid axle sleeve, at the middle part of the valve rod and is located at through there is diaphragm pad at the interface of the valve deck and valve body, in the valve
Spring is provided between lid axle sleeve and the diaphragm pad, while branch is provided with the valve body wall of the in-out end in the valve body
Pressure valve, in addition, the end for the valve rod being inserted into inside the valve deck is connected by connecting rod with controller.
It is preferred that the valve stem nut on the valve rod is provided with above the diaphragm pad.
More preferably, it is provided with spring washer between the diaphragm pad and the valve stem nut.
More preferably, a spring shim is additionally provided with the diaphragm pad, which is provided at both ends with a protrusion
Portion, gap is left between the lug boss and the spring washer.
More preferably, one end of the spring is placed in the outside of the valve deck axle sleeve and is fixed on the valve deck wall of the valve deck
On, the other end is fixed in the gap between the spring shim lug boss and the spring washer.
Beneficial effects of the present invention：The present invention makes valve by increasing by one group of spring between valve deck axle sleeve and diaphragm pad
Door can play the function of shut-off valve in certain pressure limit；Pressure valve is installed respectively in valve body in-out end at the same time, in valve
Controller is installed on bar, the pressure value of valve in-out end is fed back to the controller on valve rod by pressure valve, adjusted with this
The aperture of spool and valve seat, plays the function of regulating valve.Therefore, balanced valve of the invention is not only functionally extended,
And it is also more diversified in performance, preferably play the value of balanced valve.
Brief description of the drawings
The attached drawing for forming the part of the application is used for providing a further understanding of the present invention, schematic reality of the invention
Apply example and its explanation is used to explain the present invention, do not form inappropriate limitation of the present invention.In the accompanying drawings：
Fig. 1 is a kind of structure diagram of balanced valve of the present invention；
Fig. 2 is the partial enlarged view of spring installation position in Fig. 1.
Embodiment
It should be noted that in the case where there is no conflict, the feature in embodiment and embodiment in the application can phase
Mutually combination.Below with reference to the accompanying drawings and the present invention will be described in detail in conjunction with the embodiments.
In order to make those skilled in the art more fully understand application scheme, below in conjunction with the embodiment of the present application
Attached drawing, is clearly and completely described the technical solution in the embodiment of the present application, it is clear that described embodiment is only
The embodiment of the application part, instead of all the embodiments.Based on the embodiment in the application, ordinary skill people
Member's all other embodiments obtained without making creative work, should all belong to the model of the application protection
Enclose.
As shown in Figs. 1-2, a kind of balanced valve, including valve deck 1, valve rod 2 and valve body 3, the valve deck 1 are connected with valve body 3,
Junction is equipped with gasket, and the valve rod 2 is arranged on the inside of the valve deck 1 and valve body 3, wherein, it is inserted into the valve deck 1
Valve deck axle sleeve 4 is provided between the end of the valve rod 2 in portion and the valve deck 1, at the middle part of the valve rod 2 and is located at the valve deck
1 at the interface of valve body 3 in the top of the diaphragm pad 5 with, through there is diaphragm pad 5, being additionally provided with installed in the valve rod
Valve stem nut 10 on 2, there is spring washer 11 between valve stem nut 10 and diaphragm pad 5, meanwhile, also set up on diaphragm pad 5
There is a spring shim 12, which is provided at both ends with a lug boss 13, the lug boss 13 and the spring washer 11
Between leave gap.
The present invention is in order to enable balanced valve can play the role of shut-off valve in certain pressure limit, therefore, in original
One group of spring is added on the architecture basics of some balanced valves, which is arranged on the valve deck axle sleeve 4 and the diaphragm pad
Between 5, and one end of the spring 6 is placed in the outside of the valve deck axle sleeve 4 and is fixed on the valve deck wall of the valve deck 1, separately
One end is fixed in the gap between the spring shim lug boss 13 and the spring washer 11.
Meanwhile the present invention is in order to enable balanced valve has the function of regulating valve, therefore, in the architecture basics of original balanced valve
On add pressure valve and controller, the pressure valve 7 is separately mounted on the valve body wall of the in-out end of the valve body 3, in addition,
The end for the valve rod 2 being inserted into inside the valve deck 1 is connected by connecting rod 8 with controller 9, and can thus lead to pressure valve will be into
The pressure value of outlet feeds back to controller, and controller passes through adjusting spool and gap, that is, aperture of valve seat so that the pressure of both sides
Reach relative equilibrium.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the invention, for the skill of this area
For art personnel, the invention may be variously modified and varied.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should all be included in the protection scope of the present invention.
